EHT series carbon dioxide sensor

Series Carbon Dioxide Sensor
Before installing and using the sensor, please read this instruction manual carefully for correct use and maintenance.
An overview
Carbon dioxide sensor, this sensor converts the carbon dioxide concentration detected on site into a standard current signal output. It has good selectivity and no oxygen dependence. It is widely used in industries such as petrochemical, metallurgy, refining, gas transmission and distribution, biochemical medicine, water treatment and other industries.

Five Precautions
Please check whether the packaging is intact, and check whether the transmitter model and specifications are consistent with the product you purchased. If you have any questions, please contact our company as soon as possible. connect.
2. Before use, please confirm whether the power supply output voltage is correct, the positive and negative power supply and the positive and negative wiring methods of the product, ensure that the measured range is within the corresponding range of our company's products, and read the product manual in detail or consult our company.
⒊Please read the instruction manual carefully before use to ensure correct wiring: any incorrect wiring may cause irreversible damage to the transmitter.
Avoid installation and use in areas where heat transfer is easy and will directly cause a temperature difference with the area to be measured, otherwise it will cause inaccurate measurements.
Install in an area with a stable environment, avoid direct sunlight, stay away from windows, air conditioners, heating and other equipment, and avoid facing windows and doors
The installation height should be the height of the human body or the height of equipment that mainly requires environmental conditions
/> Prevent chemical reagents, oil dust, etc. from directly damaging the sensor. Do not use it under condensation, freezing, or high temperatures. Do not use hot or cold shock.
